38SK 3.8L STROKER KIT

Has your new JK become sluggish with the addition of heavy bumpers, winches, and taller tires but can’t spring for a super charger at the moment? The 3.8L Stroker Kit is the second best choice you can make. Not only will you reclaim the power lost to the weight of accessories; you will gain more low end and mid range torque than your stock engine originally produced. The kit comes balanced so no additional machine work is required. The cam shaft is at a maximum lift without having to have taller installed height valve springs saving you additional money on machine work. The kits are available in stock, .030, and .060 bore sizes.
